 | Top Product: Allite Super Magnesium
Weighing 33% less than aluminum and stiffer and stronger pound for pound, the Allite Super Magnesium alloy has shown its mettle in classified defense and aerospace applications. Now it's available for wider use. This material is less expensive than carbon fiber and has the lowest carbon footprint of any structural material throughout the value chain. Industry applications include home improvement, sporting goods, aerospace, automotive, biking, and beyond. Four alloy variants are available to suit welding, forming/forging, or casting. These alloys feature excellent shock-absorption properties, good electromagnetic shielding performance, good heat dissipation, and recyclability. Allite is based in Dayton, OH.

 | Researchers figure out how to combine almost any metals
Researchers in Switzerland have produced nanocrystals made of two different metals using an amalgamation process whereby a liquid metal penetrates a solid one. They think there is great potential for technological applications due to the exact controllability of the composition and size of the nanocrystals together with the possibility to combine metals almost at will.

 | Cool Tools: Leica RTC360 3D laser scanner -- LIDAR for big jobs
The new Leica RTC360 laser scanner available from Exact Metrology makes 3D reality capture faster than ever before. With a measuring rate of up to 2 million points per sec, colored 3D point clouds can be completed in under 2 min. Automated, targetless field registration and seamless, automated data transfer from site to office reduce time spent in the field. The CAD models are generally used for factory/shop floor layout plans, power plant equipment changeouts, proof dimensioning, and much more. In addition to the 3D model, full spherical HDR imagining is appended directly to the point cloud, giving a photo-realistic effect to the data and allowing for virtual walkthroughs of the areas, shareable markups, geo-referencing, and meta-tagging. So many uses.

| | Videos+: Technologies and inspiration in action | Optimize mechanical misalignments, get hidden benefits
C-Flex Couplings combine the best qualities of disc, beam, and bellows couplings in a unique and economical new design. Made to couple two rotating shafts together, these couplings can accommodate large misalignments while transmitting high torque loads with zero backlash. Benefits include lower energy usage and less-frequent bearing failure, since less stress is placed upon bearings. Constructed using high-strength hardened stainless steel or glass impregnated polyamide flexures, these couplings require no maintenance and provide years of trouble-free life, even in contaminated environments. Flexible Pivot Bearings and Super Plastic Torsional Damping Couplings also available.

Diamond vs. a hydraulic press -- which will win?
The fun folks over at the Hydraulic Press Channel are at it again. This time, they take a look at crushing raw diamonds. Will the steel press win out, or will the diamond hold its own? Some great slo-mo, close-up photography helps with the judging -- especially with the man-made diamond material, which is the second sample tested. It's a pretty interesting match-up.
